Project aims

Black-grass is a particularly pernicious and difficult to control annual weed on both, organic and conventional farms across Britain. Evolved herbicide resistance and later germination means black-grass is becoming even harder to control through normal methods of pre-emergence spraying and false seed beds.

This project aims to assess whether traditional methods of grazing winter cereals with sheep before and/or after the winter months in combination with an early sown crop can have a beneficial impact on crop weed competition without grain yield loss as a result of grazing.

ORC's role

ORC will manage a two year trial at John Pawsey’s Shimpling Park Farm, Suffolk. The two year trial will look at early and normal sowing timings and either grazed or un-grazed treatments in a winter wheat field with significant black-grass infestations.
